APPARATUS FOR STEAMING BOTTLES.

Application filed September 11, 1912.

To, all whom it may] concern Be it known that I, ANDERs ANDnnsnN Pmnsrorrn, director, a subjectof the King dom of Denmark, residing at the city of Copenhagen, in. Denmark, have invented certain new and useful Improvements 1n Apparatus for Steaming Bottles; and I do hereby declare thefollowingto be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same- The invention relates to apparatus for heating andsoakingiof bottles, vessels or the like by means of steam, which. apparatus is provided with a chamber open at its bottom, along one side of which chamber the bottles, etc, placed in bottle baskets, are successively carried upward, then to the other side of said chamber and again downward.

The invention is characterized by a steam generator or a steam supplying device arranged in the middle of said chamber, and by a lift movable up and down and arranged below said chamber, upon which lift the bottle baskets, loosely placed upon each other, for each new insertion of abasket are lifted a distance corresponding to the height of a basket, and by a device arranged in the top of. said chamber, which device during each rest of the lift carries the basket, which at the instant is in the uppermost position, to the other side of the chamber, where the baskets again loosely placed upon each other, are carried successively downward.

Further the invention'is characterized by means supporting the lower bottle basket of each pile of baskets, which means during the upward movement of the one pile make way for the basket resting on the lift and then catch and support the same, while said means during the downward movement of the lift release the lower bottle basket of the other pile and permit said pile to follow the lift, for then a little before the finish of the downwardmovement to catch and support the second from bottom of the baskets. During the upward movement in said'chamher the bottles, which are placed in the bottle baskets and which do not contain water, and which are not dipped in water, are successively heated by the steam generated in or supplied to said chamber, which steam precipitates on the outerand inner-sides of the bottles and dissolves the dirt or the like Specification of Letters Patent.

covering the same. During the movement from one side to the other of the chamber the bottles are directly acted on by the steam the temperature of which is near the boilmg point, so that all germs, bacilli, etc., present on the bottles are killed. During the downward movement the bottles are successively cooled by the rising air. The cooling can if desired be accelerated by means of water which is injected into the lower part of the steam chamber. The injected water also prevents loosened labels, etc., from re-attachment. After being treat ed in the apparatus the bottles are brought to the bottle cleaning machines for further treatment.

A constructional form of the apparatus is illustrated on the drawing.

Figure 1 is a vertical'sectionon line B B Fig. 2. Fig. 2 is a horizontal section on line A-A Fig. 1. Fig. 8 is a vertical section on line CC Fig. 2.

The apparatus consists of a steam chamber a open at its bottom but otherwise completely closed. Said chamber is arranged above a second chamber 6, which is open at its top and projects beyond the chamber a. The bottle baskets c are supplied to and again withdrawn from the chamber a through the chamber b. When the bottles are withdrawn from the last basket 0 which is withdrawn from the chamber a (at the right hand side Fig. 1), said basket is again filled with bottles and then carried to the left hand side of the chamber Z) under the supply side of the chamber a ready to begin again the circulation through the steam chamber.

A boiler (Z open at its top is arranged in the chamber a and provided with a steam supply pipe 6 through which steam is supplied for bringing the water contained in the boiler to its boiling point.

A lift is arranged below the chamber a and suspended in four chains 9 fixed to disks 72. mounted on two shafts i, on which also are mounted pinions j engaging screws 79 on a shaft m. According to the direction in which the shaft m is rotated the lift 7 is raised or lowered. The shaft m is driven by known means. From the platform 0 arranged in the chamber 6 the baskets 0 containing: the bottles are successively transferred to the lift f when the latter is in its lowermost position. The basket is placed on the lift in such a manner that it is situ ated below that part of the chamberwhich is at the left hand side (Fig. 1) of the boiler d.

V] hen then the lift is raised the bottle basket is introduced into the steam chamber. The latter is provided with latches p or the like, which are withdrawn to permit the baskets to be introduced into the steam chamber and as soon as the basket'is introduced, engage said latches p beneath the basket thereby supporting the basket. i Vhen the basket is supported by the latches 79 the lift can again be lowered. In this manner a new basket is introduced into the chamber a by each upward movement of the lift and the pile of baskets is raised a distance corresponding to the height of a basket for each new basket introduced.

At the beginning of the work the apparatus is filled with empty bottle baskets.

After each introduction of a new basket the uppermost basket of the left hand pile is carried across the shelf 00 to the right hand side of the chamber a by means of a device arranged in the top of said chamber. For instance said device consists of an angular slide 9, carried by chains 1* passing over disks 5.

By means of the arrangement illustrated in Fig. 1 the slide (1 will be carried from the left hand. side to the right hand side of the chamber a whenever a basket is moved from the right hand side to the left hand side of the chamber 72. The lengths of the two distances are exactly the same. A weight 25 or the like is connected to the chains r and is adapted to return the slide g to initial position.

When the slide 9 is carried to the right, it carries the upper basket of the left hand pipe across the shelf a; to the right hand side of the chamber a through which the baskets are again successively carried downward. The baskets are also at this side of the chamber supported by latches 77, engaging with the lowermost basket, and which when the lift is lowered release the lower basket, thercby permitting the pile to follow the lift. A little before the finish of the downward movement the latches are operated to catch the second from bottom of the baskets and support the same. In this manner the baskets, which have finished the travel through the chamber, can be withdrawn.

The latches p are operated by means of a handle 1; and levers u.

The details illustrated and described may of course be varied without departing from the principle of the invention.
